HAMMER.

Specification of Letters Patent.

Patented Mar. 14, 1916.

Application filed June 16, 1915. Serial No. 34,452.

To all whom it may concern:

Be it known that I, JAMns T. HALL, a citizen of the United States, and a resident of aco, in the county of McLennan and State of Texas, have invented a certain new and useful Improvement in Hammers, of which the following is a specification.

This invention relates to an improvement in hammers, and one of the principal objects of the invention is to provide a hammer having an auxiliary or starting claw arranged adjacent the central portion of the head'of the hammer near the point at which the hammer head is connected with the handle and adapted to be utilized in starting nails and the like which are diflioult of extraction, in such manner that the strain on the handle and hammer head will be minimized.

A further object of the invention is to provide a hammer incorporating an improved method of connecting the hammer head with the handle in such manner that it may not become accidentally detached or loosened therefrom, and in such manner that maximum strength and efliciency in the implement is attained.

A still further object of the invention is to provide an improved hammer of the class described which will be extremely simple, durable, efficient in operation, and inexpensive to manufacture.

With these and other objects in view which will become apparent as the description proceeds, the invention resides in the construction, combination, and arrangement of parts hereinafter 'more fully. described and claimed, and illustrated in the accompanying drawing in which like characters of reference indicate like parts throughout the several figures, of which- Figure 1 represents a view in perspective of a. hammer constructed according to my invention. Fig. 2 represents a view in elevation, partly in section, of a hammer made in accordance with my invention, showing Fig.3 represents a view in section taken longitudinally through the head of the hammer constructed according to my invention, parts being shown in elevation. Fi 4L represents a view in section taken vertically and trans versely on the plane indicated by the line H of Fig. 3. Fig. 5 represents a view in perspective of the end of the handle to which the hammer head is attached. Fig. 6 represents a view in elevation showing the application of the invention to a hatchet head.

The invention is applicable not only to hammers, but also to hatchets of various types and other tools of a similar nature, in which the tool head is connected with the handle and is not made integrally therewith. The invention is illustrated, however, as being applied to a hammer as this affords a simple and eifective way of setting out the invention.

In the drawings a hammer head is inclicated at 5 and is provided with the usual drivingnose 6 and extracting claw 7 At the outer edgeor face of the hammer head and substantially midway between the driving nose and the extracting claw, is formed an auxiliary or starting claw 8. It extends generally in the direction of the extracting claw 7, an opening at 9 being defined between the extracting and the auxiliary claws. The prongs 10 forming the auxiliary or starting claw converge rearwardly and the space defined between the prongs terminates at its inner end in a shoulder or abutment 11 extending longitudinally with respect to the axis of the hammer head.

At the inner end of claw 8 is formed an enlargement or cam surface 1:2 which is adapted to act as a fulcrum for the hammer when either the extracting claw 7 or starting claw 8 is being used. In Fig. 2 the hammer is illustrated as being used for drawing a nail, it being noted that the enlargement 12 is arranged against the surface of the object from which the nail is being pulled, in order to fulcrum the hammer in the manner shown. In pulling large or tightly set nails the auxiliary claw will be found to be of great use, and by reason of its formation and disposition the strain upon the hammer head and handle will be reduced to a minimum.

The arrangement and formation of the auxiliary claw when applied to a hatchet head or other similar instrument is indicated in Fig. 6, wherein 8* indicates the auxiliary claw, 12 the fulcrum or enlargement, and 9. the space defined between the auxiliary claw and the blade of the hatchet for the reception of the head of the nail to be drawn. The arrangement of the claw with respect to the hatchet head is such that the smallest amount of strain oh the implement and exertion used in pulling a nail will be other suitable fastening means extending through the metal tongue 13 and the portion of the handle lying on the opposite sides thereof. Formed at the outer end of tongue 15 and extending axially with relation thereto is a cylindrical lug 15 having an opening 16 extending diametrically through it. At the inner end of lug 15 is formed an oval shoulderor bearingv surface '17 of a size and area substantiallycoincident with the cross sectional area of the handle adja cent its inner end. The tongue 13 as it joins the surface or shoulder 17 is rounded to provide shoulders 18 on the opposite sides of the tongue and the outer ends of the handle portions lying on opposite. sides of the tongue, are formed to snugly fit against the shoulders 18. Thehammer head 5 is provided with a recess 19 of oval formation for snugly receiving the inner end of the handle, and this recess 19'is reduced at its inner end as at 20, a shoulder 21 being formed at the junction of the recesses-20 and 19. The lug 15 extends, snugly into the recessor reduced portion 20 and, the shoulder 17 fits snugly against shoulder 21.

The hammer head is transversely drilled in alinement with the recess 20 for the reception of a pin 22 which when in place'extends through the opening 16 provided in the lug 15 for securing the hammer head onto the handle. This pin is preferably threaded at one end as at 22, one of the drilled open-V. ings being threaded for the reception of the threaded portion of the pin. The Width of tongue 13, or at least that portion of it which extends into the handle head, iscoincident with the longer diameter the recess 19, so that the hammer head Will snugly engage upon it and will be prevented from loosening partially by its engagement with Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents, V V

the lateral edges of thetongue; The en gagement of shoulder 21 against shoulder 17 and the engagement of lug 15 against the Walls of the reduced recess 20 will also prevent loosening movement of the hammer head and Will insure of a tight fit of the 7 same upon the handle.

Although I have described the preferred embodiment of my invention, I may desire to make such changes in the construction, combination, and arrangement of parts thereof, as do not depart from the spirit of the invention and the scope of the appended claims.

I claim V 1. In a device of the class'deseribed, the combination of a hammer head provided with a recess therein, said recess terminating at its inner end in a reduced portion, a shoulder being formed at the junction ofthe recess and the reduced portion, a tapered metallic tongue having a shoulder formed adjacent one end engaging against the walls of the recess'entirely around the same and engaging with the shoulder provided in the hammer head, and further having a 'lu g adapted to snugly engage within the re-p duced portion of the recess in'the hammer head, said tongue being substantially of a width equal to the longer diaineterof the recess formed in the hammer head, a handle having a bifurcated inner end in which said tongue is fitted, said handle at its inner end extending within the recess in the hammer head, and a pin extending through-said hammer head'and through said lug for maintaining the hammer head on the handle. I Y

2. In a device of the class described, the combination of a hammer head having a recess therein provided with a reduced portion, a handle, a tongue carried by the handle and being provided with a lug "ex tendinginto the reduced portion ofthe recess and with a shoulder snugly fitting the main po-rtionof the recess, said handleadjacent the lug extending into said recess,

and means extending throughsaid hammer head and lug for maintaining the hammer head in place on the handle.
